Solidion Technology has filed multiple U.S. patent applications for a process that produces graphene-hosted silicon anode technology for EV batteries. Solidion said that this new method aims to enhance energy density, reduce costs, and improve battery performance in EVs.
The Role of Silicon Anodes in EV Battery Performance
EV manufacturers recognize that silicon anodes are essential for lowering battery costs and increasing energy capacity. By incorporating graphene-hosted silicon, EVs can achieve a 20-40% increase in driving range, Solidion said.
Challenges with Traditional Silicon Anode Technology
Most silicon anodes rely on chemical vapor deposition (CVD), which introduces several issues:
- Silane gas feedstock is scarce, highly explosive, and expensive.
- Current porous carbon particles hold only 50% silane-derived silicon, limiting battery energy density.
Solidion’s Breakthrough in Graphene-Hosted Silicon Anode Design
Solidion said its patent-pending process eliminates these challenges with two key ways:
- Porous graphene ball structures that accommodate up to 90% silicon, significantly increasing anode capacity.
- A silane-free silicon precursor, which improves safety, reduces costs, and simplifies storage and transport.
